Recently, Kamri et al. [1]} studied the convergence of the coordinate descent algorithm using the semidefinite programming (SDP) performance estimation method, that was introduced by Drori and Teboulle [2]}.
We will also use SDP performance estimation in our analysis, and our main contribution may be seen as the extension and refinement of the approach by Kamri et al. [1]}.
SDP performance estimation has been applied to the analysis of many iterative methods (other than coordinate descent); the interested reader may
consult [4]}, [5]}, [6]}, [7]}, [8]} and the references therein. For general background information on SDP, see e.g. [9]}.
